- Substance type: extremely pale pink powder
- Physical state: Solid

Results and discussion

Flammable solids
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Any other information on results incl. tables

During the preliminary screening test, the pile failed to ignite during the two minutes that the Bunsen flame was applied. The negative results of the screening test negated the need to perform the main test.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Conclusions:
Manganese sulphate monohydrate was found to be non-flammable in the preliminary screening tests. It was deemed unnecessary to perform further tests.
